Summary: | PROBLEM TO BE SOLVED: To suppress the movement of a steering wheel during automatic steering, and enable manually steering a wheel during automatic steering.SOLUTION: A wheel-side clutch plate 21 in linkage with a wheel-side shaft 12a of a steering shaft 12 is provided with a protrusion 27. A motor-side clutch plate 22 in linkage with a motor-side shaft 12b of the steering shaft 12 is provided with a recess 30. The protrusion 27 is inserted into the recess 30 irrespective of an engagement/disengagement state of a clutch mechanism 20. A space 31 with a predetermined size is provided in the rotation direction of the steering shaft 12 between the protrusion 27 and the recess 30. An electromagnetic coil part 23 and a coil spring 24 bring the clutch mechanism 20 into the engagement state during a manual steering state and into the disengagement state during an automatic steering state. During the automatic steering state, a motor 15 rotates the motor-side shaft 12b to steer a wheel.SELECTED DRAWING: Figure 3
【課題】自動操舵中のステアリングホイールの動きを抑制し、且つ自動操舵中に手動で車輪を操舵可能とする。【解決手段】ステアリングシャフト12のホイール側シャフト12aと連動するホイール側クラッチ板21には凸部27が設けられ、ステアリングシャフト12のモータ側シャフト12bと連動するモータ側クラッチ板22には凹部30が設けられる。凸部27は、クラッチ機構20の断接状態に拘わらず凹部30に挿入されている。凸部27と凹部30との間には、ステアリングシャフト12の回転方向に所定の大きさの間隙31が設けられる。電磁コイル部23及びコイルスプリング24は、クラッチ機構20を、手動操舵状態のときに接状態にし、自動操舵状態のときに断状態にする。自動操舵状態のとき、モータ15がモータ側シャフト12bを回転させて車輪を操舵する。【選択図】図3 |
